Is the paling at the top or bottom of plant?
A lot of people agree with and have success using he technique pimples mentioned above:
If you are using tap water at 800+ PPM I would strongly suggest filtration or at least a proper analysis. (They cost $50-$150USD, but are just as worthwhile as a TDS meter).
Canna buffers their Coco Coir with MgNO3, CaNo3, and possibly one other chemical. One of the posts above expressed the high amount of Potassium and Sulphur that is naturally occurring in Coco Coir, Canna's nutrients accommodates this through decreased Potassium and Sulfur. Canna maintains a near perfect 3 : 1 Mg: Ca ratio, and I dont suggest anyone deviate from this too much, as the entire regimen is dependent on the interactions and balance between ions/anions in our nutrient solution, the ions/anions in our growing medium, and most importantly what the end element availability is. Essentially, Canna is relying heavily on the Coco medium to provide the Potassium the plants need, and if you introduce too much of Ca and Mg at an unknown rate, that Potassium and possibly other elements may not be available to the plants.
I personally used Cal-Mag Plus by Botanicare when i was supplementing Canna, it also has a 3:1 Ratio. There is a strong argument that an increase of the base nutrients is just as/more effective than trying to supplement CaMg.
1ML/Gal Canna = 12Ca-4Mg
1ML/Gal CalMag = 9Ca-3Mg
Until you've ran canna once or twice, I'd suggest just increasing the base nutrients, it'll give you additional micronutrients that aren't present in the CalMag products.
When increasing feed rate:
Increase by 0.5-1ML/Gal at a time, feed at new rate for 3 days, look for positive progress on 4th day. If they have not recovered or the deficiency is still progressing, increase feed rate again by 0.5-1ML/Gal, feed at new rate for 3 days, look for positive progress on 4th day. Etc.
I'm getting ready to run a Canna remake alongside the Canna Line in vegetative space, I'll let you know if unnoticed any Mg deficiency. I honestly feel like Canna nutrients "light-feed/soft-water" schedule doesn't need to be deviated from during vegetative, but I'll let you know how my experiment works out.

.....if you cant get a report on EXACTLY whats in the water...just make it 0.2 to 0.4 EC whether you have to take some EC out with a reverse osmosis filter (too hard) and add back until you hit 0.2 - 0.4 target or add up (too soft) with a simple calmag product. Just about any of them will do. Then add your base nutrient and pH adjust according to substrate medium and cultivar. You should be good to go.
